Please read through this manual carefully before beginning use, so that you will be able to take full advantage of your power amplifier’s superlative features and enjoy trouble-free operation for years to come. After you have read the manual, keep it in a safe place for reference when needed.

NOTE

•When there are differences in the specifications of the XMV4280 and the XMV4140, this manual will use curly brackets { } to enclose information that applies only to the XMV4140.

(Example: 280W {140W}).

•Unless otherwise specified, illustrations are taken from the XMV4280.

Features

The XMV is a multi-channel power amplifier with the following features.

•Both high-impedance and low-impedance connections are supported

Both high-impedance connections to 70V/100V lines and 4Ω/8Ω low-impedance connections are supported. A rear panel DIP switch allows this setting to be specified for every two channels.

•Newly-developed “Double Power mode”

The newly-developed “Double Power mode” doubles the amplifier output of each channel when low-impedance connections are used.

* The number of available channels will be halved.

•Settings can be made via application software

Although settings such as mute on/off and attenuator values can be edited from the panel of the amplifier itself, you can use an MTX series matrix processor and computer to edit the settings of multiple XMV units.

•Support for the newly-developed “YDIF” digital audio transmission format

This allows up to 16 channels of audio and word clock to be transmitted and received via an Ethernet cable.

This model can receive four channels of audio signals via YDIF.

•High efficiency

The newly-developed output circuits allows high efficiency.

Precautions for Rack Mounting

This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. When mounting the unit with other XMV unit(s) or other device(s) in an EIA standard equipment rack, internal temperatures can exceed the specified upper limit, resulting in impaired performance or failure. When rack mounting the unit, always observe the following requirements to avoid heat buildup:

•When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave more than 1U of space between the XMV and other equipment. Also either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup.

•To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If the rear of the rack can’t be left open, install a commercially available fan or similar ventilating option to secure sufficient airflow. If you’ve installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and/or fan unit manual for details.

Setting the switch to the downward position turns the power off. If the switch is in the upward position and the [POWER] indicator is blinking, the unit is in standby mode.

CAUTION

•To ensure that high-volume noise is not output from the speakers, power-on the equipment starting with the audio sources, then the mixer and processors (such as the MTX), and finally the amplifiers. Reverse this order when turning the system off.

•Rapidly turning the power switch ON and OFF in succession can cause the unit to malfunction. After turning the power switch OFF, wait for about 5 seconds before turning it ON again.

•If you modified parameter settings, do not turn the power switch OFF for at least one second. Otherwise, the changes to the settings may be lost.

w[PROTECTION] indicators A/B/C/D

When the protection system is active, the indicator will light orange. If the audio output is muted, turn off the power and wait for the XMV to cool before turning the power on again. The protection circuit will operate in the following situations.

If the amplifier overheats and the output limiter operates

The speaker output will be attenuated if the heat sink of the amplifier section exceeds 80°C (80%), and will be muted if the heat sink exceeds 90°C (90%). The [PROTECTION] indicator will light at 80°C (80%) or higher.

If the power supply overheats and shuts-down

The fan will rotate at high speed if the power supply section exceeds 90°C, and the analog circuits will shut down if it exceeds 100°C.

The [PROTECTION] indicator will light at 100°C or higher.

When overcurrent is detected

If for any reason the impedance falls below rated, the speaker output is muted to prevent overcurrent; muting will be cancelled after approximately one second. If overcurrent is detected after muting is cancelled, the output will be muted again.

If DC output is detected

The power supply section will be shut down.

If excessive total current or maximum current is detected

The output signal will be compressed.

e[LIMIT] indicators A/B/C/D

When the limiter operates, the speaker output will be limited and the indicator will light red. Lower the attenuator value so that the limiter does not operate. The limiter will operate in the following situations.

•When an instantaneous input overload is detected

•When an input overload has been occurring for a specific duration

•When the heat sink of the amplifier section exceeds the allowable temperature

r[SIGNAL] indicators A/B/C/D

The indicator will light when the input from the analog input connector / [YDIF] connector or the output from the [SPEAKERS] connector rises above a certain level.

If the [SIGNAL] indicator is set to show the input from the analog input controller / [YDIF] connector, it will light when the signal level is greater than -40 dBFS.

Switch 4 (LED DIMMER)

This specifies the brightness of the front panel indicators and display.

DIP Switches	Setting	Description
	OFF	Normal brightness.
		Reduced brightness. Use
	ON	this setting if the indicators
		and the display are too
		bright.

NOTE

The brightness of the [POWER] indicator will not be reduced.

Switch 5 (PANEL LOCK)

This specifies the front panel lock setting (locks all panel operations including the [MUTE] button and attenuation adjustments). By selecting the LOCK setting after you’ve completed all settings, you can prevent the volume or mute settings from being inadvertently changed.

Even if the LOCK setting is selected, you can temporarily unlock the panel by pressing the [FUNCTION] button and the [SELECT] A button. The panel will be re-locked when one minute has passed without any operation being performed, or when you once again press the [FUNCTION] button and the [SELECT] A button, or when you turn off the power.

RESUME

The unit will start up normally.

The internal memory will be initialized. For details on the

INITIALIZE memory that will be initialized, refer to “Initializing the Internal Memory” (page 22).

Controls and Functions

@1Analog input connectors

These are Euroblock 3-pin analog audio input connectors. For details on settings for receiving audio signals via the analog input connectors, refer to “List of Front Panel Operations” (page 20).

For details on how to attach Euroblock connectors, refer to the “Setup” section entitled “Connecting the analog inputs (Euroblock)” (page 13).

@2[SPEAKERS] DIP switch

This DIP switch makes settings for the XMV’s amplifier in groups of two channels.

Switches 1 through 4 specify the output setting for channels C/D, and switches 5 through 8 specify the output setting for channels A/B.

Use these switches to make the following settings.

			Switches 1–4
	Description		(channels C/D)
			Switches 5–8
			(channels A/B)
		280W{140W}, 8Ω
	Low-impedance	560W{280W}*, 8Ω
	Connection	280W{140W}, 4Ω
		560W{280W}*, 4Ω
	High-impedance	70V, 250W{125W}
	Connection	100V, 250W{125W}

*If this setting is chosen, input/output will be disabled for channels B and D.

Low impedance connection / high impedance connection (switches 1 and 5)

These select either a low impedance connection or a high impedance connection. Set them as appropriate for the connected speakers and the way in which the speakers are connected. For details on connections, refer to “Highimpedance and Low-impedance Connections” (page 25).

Impedance (switches 3 and 7)

When using a low impedance connection, set these as appropriate for the impedance of the speakers that are connected. Check the specifications of the speakers.

For example if two 8Ω speakers are connected in parallel, the total impedance will be 4Ω.

Double Power mode (switches 4 and 8)

When a low impedance connection is used, these switches specify the output of the amplifier. If the 280W {140W} setting is selected, input/output is enabled for both channels. If the 560W {280W} setting is selected, the output from the amplifier will be doubled, but input/ output will be disabled for channels B and D.

70V/100V (switches 2 and 6)

When a high impedance connection is used, these switches specify the maximum output voltage (Vrms) of the amplifier.
